Application of Dual “Kite” Myomucosal Flaps for the Repair of Medium Lip Defects

To investigate the application of dual "kite" myomucosal flaps (subcutaneous pedicle advancement flap) for the repair of medium lip defects (one-third to one-half lip width). Dual kite myomucosal flaps were designed in the adjacent area of the defect in 17 patients with medium lip defect with the principle of using homogenous tissue as far as possible without affecting local anatomical units. The follow-up time was 3 to 24 months; 16 patients showed primary wound healing, and 1 patient showed prolonged healing. The blood supply of the myomucosal flaps were reliable. The myomucosal flaps were smooth, with no proliferation of scars, and the local appearance was good. The dual kite myomucosal flaps provide a reliable method for repairing medium lip defects, decreasing the need for additional excision of normal skin tissue, and reducing skin scar.
